I'd hate to have to re-invent the wheel for common forms everyone needs.
An online repository of user-submitted forms, importable into the app, would make your app more marketable--even more useful right out of the box, so to say.
Perhaps it could be a site users register for. Once registered, allows users to upload their form with a description, keywords, and iPhone/iPod touch screenshots attached.
Users could search for forms meeting their needs and download. Import via the 'Import' function (instead of importing csv, mechanism to import a form itself).
